From: Brian


Thank you so much for checking in.  I was actually telling a bunch of the firefighters here what a cool company you guys have.  There are some dura max guys here and I have sent them your way.

It’s all about the time you took with my purchase that will keep me coming back for the tuning and more accessories. 

The install was a piece of cake, the parts are exceptional.  Everything is working very well.


Thank you!"

May 26, 2016
From: Daniel

"Rob, ATP, and co. ,
When Mike Porcaro answered the phone at ATP when I first decided that after endless hours of scouring the forums, picking the minds of reputable members, going through the arduous task of dissecting all the good information from the bullshit, little did I know that I would walk away from my first experience with ATP beyond satisfied, but also gain someone that I can honestly call a friend.

You don't find that level of honest, insightful, and agenda free service these days. There's nothing wrong with promoting products you truly believe in, but it becomes blatantly apparent when someone is there just to empty your pocket. My experience with Mike from my first phone call is what had me requesting him, and only him to continue to assist me with my account.
That's not to say that the other employees and sales reps at ATP aren't of the highest quality.

I'm just someone who knows when and if you're lucky enough to find a person like Mike, a person who treated my truck like it was his own, who patiently, professionally, and courteously dealt with all the hesitant & reluctant thoughts that myself, and I'm sure most of us who are truly passionate about this life have....well that was apparent from the time I was merely a potential client he may never hear from again, to the time I handed over my credit card number and told him I truly trusted him with my hard earned money.

I never once had an uneasy feeling or second thought throughout this 3 week process, and that was due to the fact that I was updated and informed consistently, and most importantly, honestly. I never had to reach out and inquire to where things were, because my inbox or voicemail already had a message from Mike to ease my mind. If a product was back ordered, he didn't tell me it was out for shipping. The respect and appreciation I have for that type of sincerity is endless.

Most representatives know how to regurgitate the label of a product. It's easy to tell the difference between those and the ones that have lived and breathed this shit for years and have an internal database that extends beyond the phone, into the garage, and out into real world application.
THOSE are the guys I want guiding my decisions, and THAT is exactly what I got from Mike P. He handled my account from day 1, to the day I'm writing this email. An email that was something I willingly offered as it was the very least I could do to show my appreciation for both him, and ATP Trucks.

My parts are in the mail. The transaction is complete and I could walk away without taking the time to write this. But I'd be doing a great disservice if I was to not commend Mike Pocaro for being a great representative of ATP, a great representative of Diesel Performance, and more importantly just a good man who was true to his word, a man who left me a more educated person in this field, and someone I will not only be happy to build a truck with, but a damn good friendship as I continue my business with this outfit. Thank you Mike."

May 11, 2016
From: Cooper

"Hey guys. I just wanted to give a huge thanks to Mr. Mike Porcaro for all the awesome support he gave me throughout everything. He was super helpful, patient, and just absolutely outstanding to go out of his way to see that I was taken care of completely. I have never used ATP Trucks before, till I started helping a co-worker with his 2005 LLY, and I have never been helped so much by any customer service group. I have been in the diesel performance game since about 2007, and not a single company or person has helped and walked me through things as well as Mike. I greatly appreciate all that you guys have done for my co-worker and I. The truck has never ran better!"

April 06, 2016
From: John

"It was our pleasure you guys continuously go above and beyond anytime we need answers or have a problem. We have run into problems with things before that we have contacted the manufacturer of an item and cannot get answers from them. You guys are always ready to help no matter what the problem or who we talk to, you should be very proud of your business and your staff. You guys have a business ethic that is very rare to find anymore. What is really great is you guys are not just selling parts you use what you sell and have a real interest in the business you are in. Again I thank you for your time and patience you and your staff have shown us and I wish we were a little closer but one day we will meet in person."

March 17, 2016
From: Devin

"Hey Ryan,
I talked to you today about issues. Your tech wasnt available but you said you would have him call me and within 5 min he gave me a call. I don't remember his name, Cody? Anyway I just wanted to applaud you guys on your customer service and even though the problem was on my side everyone I spoke to was very helpful. The problem was that I did not get the ground wire seated enough but the 5th time was the charm. LoL. I recommended you guys to a friend also he is getting ready to buy efilive for his lmm"

March 15, 2016
From: J.C.

"I just wanted to drop you a note and thank you and ATP for all of your assistance with my project. Just about everything I've done recently with my truck involved a lot of "first time" work. ATP's commitment to customer service and quality products lives up to the hype that I've read in countless discussion forums.

Thanks again and take care."

My dad (Jim L...) was the guy that came in last week or so ago and camped out while you guys did some work to his truck. He had really nice things to say about you and your team there at ATP. He said it was nice of you to let him camp out in the conference room and was glad that you guys stayed late to finish his truck so he could make it to Alaska in time. I was glad to hear this because i referred him to you and he is not one to have other people work on his stuff. he is DIY kinda guy but he had a good experience with you guys.

thank you for the great products and service. i will be purchasing more stuff soon."

The reason for this email is to thank you and your staff.

The experience with your company was great after calling many times over the last couple months with a lot of questions about what I should do and talking to everyone on your staff I think all I can say is thank you. Everyone was willing to take the time and explain everything, they were very nice and helpful. As a small business owner myself I can appreciate how great of a group of people that you have. No one wanted to make me wait to talk with the person that I started with they were all willing to help just like the last it has been the best customer service I have ever had.

Thank you again and have a great weekend"
